Which type of firewall may lead to connectivity issues during the Port Scan phase?

The correct answer is logical firewall because this type of firewall operates at the operating system or application layer, controlling traffic based on configured rules rather than physical hardware locations. During the Port Scan phase of discovery, a logical firewall can block or restrict specific ports or protocols, potentially leading to connectivity issues.

Logical firewalls can impose restrictive access controls that may not adhere to the expected open ports required for discovery operations. This can result in incomplete data collection or failure to establish connections to necessary services on the target systems.

The other types of firewalls, such as physical and network firewalls, primarily operate at the network perimeter and are less likely to discriminate based on port scanning compared to logical firewalls, which can impact individual systems based on local configurations. A software firewall, while it could also block traffic, typically relates to specific applications rather than the broader scope of operations that a logical firewall might manage.
